Final Fantasy Tactic War of the lions.
Combat dymanics are much better, it has a better grasp of distance and weapons than D'arc. It doesn't cheat you by scamming you out of 95%+ strikes and miraculously making 18%- strikes against you.
Only thing D'arc has over it is story.
Note this is my opinion as other will say Wot's story is A-mez-in.
p.s
I was actually thinking about doing another run on Wotl as the game is that good, it's on psp by the way incase you are wondering.
